Ethanol is the systematic name defined by the International Union of Pure and Applied Chemistry (IUPAC) for a compound consisting of alkyl group with two carbon atoms (prefix "eth-"), having a single bond between them (infix "-an-"), attached functional group-OH group (suffix "-ol").[1] The "eth-" prefix and the qualifier "ethyl" in "ethyl alcohol" originally come from the name "ethyl" assigned in 1834 to the group C 2H 5- by Justus Liebig. He coined the word from the German name Aether of compound C 2H 5-O-C 2H 5 (commonly called "ether" in English, more specifically called "diethyl ether").[17] According to the Oxford English Dictionary, Ethyl is a contraction of the Ancient Greek αἰθήρ (aithḗr, “upper air”) and the Greek word ύλη (hyle, substance).[18] The name ethanol was coined as a result of a resolution that was adopted at the International Conference on Chemical Nomenclature that was held in April 1892 in Geneva, Switzerland.[19] The term "alcohol" now refers to a wider class of substances in chemistry nomenclature, but in common parlance it remains the name of ethanol. The Oxford English Dictionary claims that it is a medieval loan from Arabic al-kuḥl, a powdered ore of antimony used since antiquity as a cosmetic, and retained that meaning in Middle Latin.[20] The use of "alcohol" for ethanol (in full, "alcohol of wine") is modern, first recorded 1753, and by the later 17th century referred to "any sublimated substance; distilled spirit" use for "the spirit of wine" (shortened from a full expression alcohol of wine). The systematic use in chemistry dates to 1850. History-------------------------
